Got to orbit today.

Good job! Paraphrasing a certain rather famous author, half of RO's difficulties are now behind you=)

 

Anyway, I reckon I'll spam this thread some more, here's a year-and-a-half old thing recently rebuilt for 1.1.3. Not terribly useful, but it's RP-0 stock so if anyone wants to play with it it's in my craft file folder.

Eaglet

Basically a small ICBM with the warhead and decoy attachment points swapped for payload interfaces.There's three of them and, oh right, no fairing. Like on a couple of Russian sea-launched missiles, everything has to fit in the last interstage. After orbital insertion, the upper stage discards its main engine and can maneuver using nose-mounted post-boost thrusters before the satellites detach. Due to proximity to the engine, they have to be covered by protective shrouds during launch, but...eh. Would've made it even more useless.

Payload: 100 kg to low Sun-Synchronous orbit, ~150 kg to LEO from Wallops?

GLOW: 40.0 t

Cost: 24.4 million in 2017 USD. But at least the military pays for it...

Upper stage after engine ejection, two satellites visible. This is an old pic from 1.0.something, but I didn't change much.

 

In other news, you'll get to see a crewed circumlunar mission soon, along with a couple of more modern vehicles=)

1.2 pre release...

Alright since I don't want to double post, here is my old lunar lander.

So first of all, I dismissed the TWR since I thought it wouldn't matter when the Mun's surface gravity is 1.62 m/s. Wrong. The Apollo descent engine is weak as heck. Glad I never flew the mission. Second, I found out when I was trying to correct the Launch vehicle's second stage to be able to have enough DV to get the whole spacecraft to the moon, (Orbiter included) That the entire Apollo spacecraft weighed basically as much as my lander here and here I am trying to build a thing that will get 60 tons to the Moon. That just ain't happening. So I redesigned it.

(Ignore the bottom bit, just a bit of extra life support and avionics)

Weighs about the same as the Apollo lander, just a lot less DV which is ok since I didn't need that much anyways. Much more powerful engine, just not as efficient. Uses a slightly less heavy Gemini capsule and not as much life support. The previous one had food for at least 100 days. And I used a few SSTU parts along with the FASA and procedural parts.

And I thought since I'm copying the NASA constellation mission plan, why not use the same rockets?

Ares V made with Proc. Parts, Proc. Fairings and SSTU. Not that accurate but hey, at least I got the diameter right, right?

But that's it for now.

Dunno if you can get it for 1.1.3 still.  That's the last stable version I think.  You just miss out on 1.2 features that I think are very useful for RSS/RO like auto-strutting and fuel flow management.

You just have to find KSP version 1.1.3 somewhere.

As far as myself, I installed RSS/RO last year well before 1.2 using CKAN.  I copied the game from Steam, removed the mods I was using there, and then installed RSS/RO.

At least for RO it is easy to fall back to a previous version. It depends on the mod publisher for the "third-party" ones.

I for one am still on 1.1.3. But yes, the prerelease apparently works if you take some time to set it up manually

Looking good! What are you using for power generation? Batteries are fine if you plan to stay on the surface for a day or two, but for longer missions fuel or solar cells would be the lighter option.

If I didn't add any, I would use small fixed solar panels. As for the orbiter which I haven't posted here, that will have some slightly bigger solar arrays for power generation. So I'm still tweaking. I haven't added antennae to either craft yet either. But I am very close to completing the preparations for the mission! 

Actually, look near the top of the landing capsule. I did add some small solar panels there. I also added some batteries next to the second stage of engine.

Good luck, and keep us posted! But a crewed Gemini capsule sips 2 kilowatts and IIRC the small panels give like 40 watts apiece when fully lit? Better double up on those batteries

You're right I should pay more attention to my power generation. RO power is different than stock. And if you're interested, I have a mission report that I will post my progress on every few days or so. I will post most stuff there but occasionally, I will post here.

[Nittany Tiger]

Any tips to reduce floppy rocket syndrome?  During some runs with my Saturn VB using my kOS script, after SRB jettison, my rocket loses all structural integrity and starts to gyrate around it's z-axis.  This doesn't always happen, but I don't know when or why it does.

I have attempted to strut up the weak joints, but that doesn't seem to help the problem.

[Firemetal]

@Nittany Tiger Struts usually work for me, not sure. Maybe a kraken attack related physics glitch?

 

Hopefully flying LLM-1 tomorrow, just debating whether to do it in one or two launches.

Here is the lunar orbiter and its launch vehicle.

This will launch if I fly the two launch mission and dock to the lander & transfer stage in LEO before executing TLI. Now here is the Single launch configuration.

 

This I thought might work since it is only adding around 20 tons to a 250 ton second stage & lander and 3115 ton launch vehicle, payload, second stage and all. Except instead of acting like an Ares V, it acts like a Saturn V. Same mission plan basically. Though I get more DV if I do it with two launches. This has about 1100 to make mistakes with.

 

But I kind of like the idea of one launch more. Quicker, less tedious, more efficient. The only thing the two launch config does better is DV. But they both have more than enough to do it.

 

But that's it for now.

@Firemetal I have 6x struts on the weak parts already.  Again, the flexing seems to only happen sometimes.

 

 

This is a time I wish I had the autostruts of 1.2

Yeah, I think it is a Kraken related glitch. Once I built a Saturn V and made it very rigid. I even used autostrut but it kept wiggling out of contro and blowing up at a certain point during launch. Then I launched it again and it didn't. Keep in mind that this was stock. The only way I could explain it was the Kraken.

Fire

[Nittany Tiger]

It's probably a Kraken, but it's not one that strikes every time, so I can get my craft to orbit if I can psych the Kraken out, or somehow load the ship so it doesn't get floppy after SRB sep.

To be honest, I will have to watch out for the Kraken at all times on this mission.  I've had it strike once during testing in orbit of the propulsion module and command module docked after firing the MS-II engines.

It is fairly regular to use KJR when playing with RSS, reduce/eliminate wobble.

[F]irst teaser of a hot rear end, more pics and a DL link following soon

In unrelated news, I finally managed to get into orbit around Venus. With two craft, no less! Also, the most recent mission report is here in case anyone wants to read those.

[Ravenchant]

Pfft, this thread needs more replies. @Firemetal, how is your landing coming along? 

Anyway, here's Kaon:

It was supposed to lift around 12 tons to low orbit, and K-mesons have approximately half the rest mass of protons, hence the name. But it actually does quite a bit more, 15.5 tons to a 65° inclined low orbit. The lower stage, block-C, has 4 NK-15 engines. I couldn't get them to fit on a 4m core, so they are arranged in a thrust structure underneath the 2m kerosene tanks. Also, they magically can gimbal (sekrit dokuments tovarischi xaxaxa). The insulated central tank is 4m across and holds liquid oxygen. The upper stage, block-L, has a single NK-19 engine burning for almost 7.5 minutes and starts out at a paltry 0.57 TWR when flying with maximum payload.

Chinese-style hotstaging (the interstage remains attached to stage 1)

Test payload. Roll control of stage 2 is via nitrous oxide thrusters, but they're pretty weak.

As for craft files: The Kaon one is here, I think RP-0 and SovietRockets are enough for it to load. I also added two launch towers to the subassemblies folder, one with arms as seen below and the other without it to remove the IR dependency.

That rocket, btw, launched the TLI stage for a crewed Moon flyby, with the Gemini launching separately. Here's the whole complex just before docking:

Yeah............ Experiencing some technical difficulties. I decided to build another lander except this was a direct land and return one. 180 tons. Then I built a scaled up N1 to get it to the Moon. It didn't go so well. Returning to the Apollo style mission. I'm going to go back to my original plan. Do it like the Ares missions. The question is whether I build another lander or not. But I haven't given up! I will post updates soon.

@Ravenchant, awesome crafts!
Where did you get these solar panels? 
 

Spoiler

 

[Ravenchant]

@DrLicor, they come with RO as far as I know. Each wing is one large-ish fixed panel and two small ones.

[DrLicor]

@Ravenchant, ohh I thought it was one part  thanks!

[Ravenchant]

Yeah, it's easier to see from the underside  They're attached to a thing procedural tank and offset, the tank itself is mounted on an IR hinge which sits on a stubby procedural wing pylon for clearance (not the same probe, but the panels are identical).

I just launched my first space station in my new RP0 carreer, and I'm quite happy with the looks of the LV:

First stage of 5 E-1s

Second stage powered by 4 LR105s

4 AJ10 engines placed the 16 tonne station in a 600 x 600 km orbit.

 

The rocket has a TWR of 1.15 on the pad, which is not exactly great, but with some careful piloting you can get 16+ tonnes of payload to LEO.
